We identified 13 studies that met inclusion criteria for our review (7 randomized controlled trials and 6 observational studies). We divided studies based on intervention and summarized evidence narratively. Benzodiazepines decrease alcohol withdrawal seizure recurrence and treat other alcohol withdrawal symptoms, but no clear evidence supports the use of one benzodiazepine over another. It is unclear if symptom-triggered benzodiazepine protocols are effective for use in the ED. More evidence is needed to determine if phenobarbital, with or without benzodiazepines, can be used safely and effectively to treat alcohol withdrawal in the ED.

Interventional studies with or without a comparator group, including randomized controlled trials (RCT) and non-randomized trials, as well as observational cohort studies that evaluated an intervention. We excluded review articles and case reports, studies published prior to 1980, non-English publications, and non-human studies. “Clinical management of alcohol withdrawa[…] A systematic review.” Industrial Psychiatry Journal, December 2013. (3) Ethanol potentiates GABA-A receptor transmission, increasing chloride influx, similar to benzodiazepines.

Alcohol withdrawal seizures are a strong risk factor for progression into a severe withdrawal state, with subsequent development of delirium tremens in up to 30% of cases if untreated (68). This is the most severe manifestation of alcohol withdrawal syndrome and progresses 48 to 72 hours after consumption cessation, lasting up to 14 days, with a mortality of 1% (39; 25). Seizures are a rare but serious complication that occurs during alcohol detox. Seizures can happen as early as day two during detox, but delirium tremens (DTs) can appear on days 3-4. During the DTs, the person has a high risk of having alcohol withdrawal seizures.

The first consideration in a patient with possible alcohol withdrawal seizures is the exclusion of life-threatening causes of seizures, as described in the differential diagnoses above (37). At the same time, a history of chronic alcohol abuse must be sought and the patient should be classified as having one of the categories of alcohol-related seizures (37). As more than 90% of alcohol withdrawal seizures occur soon after the cessation of sustained drinking, whereas other withdrawal symptoms develop gradually, withdrawal may not be readily evident in the beginning (25). Most alcohol withdrawal seizures occur between 12 and 48 hours after a sharp decline in blood alcohol concentrations. Some alcoholics drink to control the tremulousness that sometimes precedes seizures; therefore, the smell of alcohol on the breath does not rule out the diagnosis of alcohol withdrawal seizures. Typically, alcohol withdrawal seizures are brief, recur within a period of 6 to 12 hours, and are self-limited.

Alcohol Withdrawal Seizure

In animals, benzodiazepines have yielded variable effects, in some cases slowing withdrawal-induced kindling, and in other cases, causing paradoxical worsening (65,66,89). Whether other agents used in the treatment of alcohol withdrawal have antiepileptogenic potential remains to be determined. The spectrum of alcohol withdrawal symptoms ranges from such minor symptoms as insomnia and tremulousness to severe complications such as withdrawal seizures and delirium tremens. Although the history and physical examination usually are sufficient to diagnose alcohol withdrawal syndrome, other conditions may present with similar symptoms.

Delirium tremens is estimated to come with a 35% risk of death if you go through it without treatment. The reason for this is that heavy continued drinking can actually change the chemical makeup of the brain to the point where it thinks that it has to have alcohol in order to function properly. When the brain has reached that level of alcohol dependency and you stop giving it what it thinks it needs, it reacts in a negative way.

Can alcohol trigger seizures?

Not everyone who experiences alcohol withdrawal will experience delirium tremens. Alcohol use disorders cover a range of severity from mild to moderate to severe. Someone with a mild-to-moderate alcohol use disorder may have a problem with alcohol without developing significant dependence. In such cases, alcohol withdrawal may not occur when they cut back or quit drinking. However, about half of people with alcohol use disorders will experience withdrawal symptoms.

In addition, alpha 2-adrenergic agonists (clonidine), beta-blockers, or dexmedetomidine should not be used in the prevention or treatment of alcohol-withdrawal seizures (70). The severity of alcohol withdrawal symptoms progressively increases over years of alcohol abuse, and repeated detoxifications augment the likelihood of alcohol withdrawal seizures (83,84). Similarly, studies in rodents have shown that repeated alcohol withdrawal experiences increase the severity and duration of subsequent withdrawal seizures (85,86). These observations have led to the view that alcohol withdrawal causes permanent epileptogenic changes in brain systems relevant to ethanol withdrawal seizures—a type of kindling phenomenon. Indeed, in accordance with the central role of the IC in triggering alcohol withdrawal seizures, multiple alcohol withdrawal episodes in rats facilitate the development of IC kindling (87,88). There is no recognized treatment to slow or prevent this kindling process.

Protracted withdrawal

For example, in mice undergoing alcohol withdrawal, gabapentin at doses of 50 to 100 mg/kg decreased the incidence of AGS (Watson et al., 1997). Vigabatrin may also be of value in alcohol withdrawal, but data from animal studies are not available as yet (Stuppaeck et al., 1996). Patients with severe alcohol withdrawal symptoms and all those with seizures during previous alcohol withdrawal episodes have higher risk for https://ecosoberhouse.com/article/alcohol-withdrawal-seizure-causes-symptoms-treatment/s and may benefit from seizure preventive treatment (19). When pharmacological treatment is necessary, benzodiazepines should be chosen for the primary prevention of seizures in a person with alcohol withdrawal. Benzodiazepines are effective in the primary prevention of ethanol-withdrawal seizures during alcohol detoxification.

Thus, in addition to benzodiazepines as the first choice in the pharmacological management of such seizures, all such patients should be given thiamine during hospitalization, regardless of nutritional state. In this article, the authors explain the clinical presentation, pathophysiology, diagnostic work-up, and management of alcohol withdrawal seizures and provide clues to the differentiation of withdrawal seizures from seizures due to epilepsy. Anticonvulsant therapy is usually not required for alcohol withdrawal seizures. Neuronal plasticity mechanisms may play a role in the susceptibility to alcohol withdrawal seizures in humans and rodents. In humans the number of detoxifications, not the absolute amount of alcohol intake, best predicts the likelihood of subsequent alcohol withdrawal seizures (Ballenger and Post, 1978). Similarly studies in rodents have shown that repeated alcohol withdrawal experiences increase the severity and duration of subsequent withdrawal seizures.

Most patients have a similar spectrum of symptoms with each episode of alcohol withdrawal. Prophylactic therapy is recommended in all patients with known or suspected alcoholism, malnutrition, or frequent vomiting. According to a Cochrane review, there is insufficient evidence to guide the selection of dose, frequency, route, or duration of thiamine for prophylaxis or treatment of Wernicke-Korsakoff syndrome (12). Parenteral administration of 250 mg thiamine should be given in the emergency room before any carbohydrates are started to prevent Wernicke-Korsakoff syndrome, and this dose should be continued daily for 3 to 5 consecutive days (60). Oral administration is insufficient, as the intestinal thiamine absorption is too low and may be severely impaired in alcohol abuse (21). In alcoholics that have consumed alcohol for a long time, withdrawal from alcohol can be a serious problem, as withdrawal seizures can occur and cause serious harm or even death.
